Generating barcodes utilizing cryptographic techniques

Abstract

Various embodiments are generally directed to secure generation of barcodes using cryptographic techniques. An application may receive a request to generate a barcode. The application may receive encrypted data from a communications interface of a contactless card associated with an account. The application may receive, from a server, verification of the encrypted data and an encrypted authorization token associated with the account. The application may generate the barcode utilizing the encrypted authorization token.

What is claimed is: 
     
       1. An apparatus, comprising:
 a processor circuit; and 
 a memory storing instructions which when executed by the processor circuit, cause the processor circuit to:
 receive, by an application executing on the processor circuit, a request to generate a barcode; 
 receive, by the application, encrypted data from a communications interface of a contactless card associated with an account; 
 receive, by the application and from a server, verification of the encrypted data and an encrypted authorization token associated with the account; and 
 generate, by the application, the barcode utilizing the encrypted authorization token. 
 
 
     
     
       2. The apparatus of  claim 1 , the memory storing instructions which when executed by the processor circuit, cause the processor circuit to:
 display the barcode on a display device. 
 
     
     
       3. The apparatus of  claim 1 , wherein the barcode is pre-configured by the authorization token to authorize a single transaction. 
     
     
       4. The apparatus of  claim 3 , wherein the barcode and the authorization token are configured to expire after the authorization of the single transaction. 
     
     
       5. The apparatus of  claim 4 , wherein the transaction is a payment transaction and the authorization token is a payment token, and wherein the payment token is associated with a monetary limit. 
     
     
       6. The apparatus of  claim 1 , the memory storing instructions which when executed by the processor circuit, cause the processor circuit to:
 decrypt, by the application, the encrypted authorization token to authorize a transaction. 
 
     
     
       7. The apparatus of  claim 1 , the memory storing instructions which when executed by the processor circuit, cause the processor circuit to, prior to receiving the verification of the encrypted data:
 transmit, by the application, the encrypted data to the server. 
 
     
     
       8. A non-transitory computer-readable storage medium storing instructions that when executed by a processor circuit cause the processor circuit to:
 receive, by an application executing on the processor circuit, a request to generate a barcode; 
 receive, by the application, encrypted data from a communications interface of a contactless card associated with an account; 
 receive, by the application and from a server, verification of the encrypted data and an encrypted authorization token associated with the account; and 
 generate, by the application, the barcode utilizing the encrypted authorization token. 
 
     
     
       9. The medium of  claim 8 , storing instructions that when executed by the processor circuit cause the processor circuit to:
 display, by the application, the barcode on a display device. 
 
     
     
       10. The medium of  claim 8 , wherein the barcode is pre-configured by the authorization token to authorize a single transaction. 
     
     
       11. The medium of  claim 10 , wherein the barcode and the authorization token are configured to expire after the authorization of the single transaction. 
     
     
       12. The medium of  claim 11 , wherein the transaction is a payment transaction and the authorization token is a payment token, and wherein the payment token is associated with a monetary limit. 
     
     
       13. The medium of  claim 8 , storing instructions that when executed by the processor circuit cause the processor circuit to:
 decrypt, by the application, the encrypted authorization token to authorize a transaction. 
 
     
     
       14. The medium of  claim 8 , storing instructions that when executed by the processor circuit cause the processor circuit to, prior to receiving the verification of the encrypted data:
 transmit, by the application, the encrypted data to the server. 
 
     
     
       15. A method, comprising:
 receiving, by an application executing on a processor, a request to generate a barcode; 
 receiving, by the application, encrypted data from a communications interface of a contactless card associated with an account; 
 receiving, by the application and from a server, verification of the encrypted data and an encrypted authorization token associated with the account; and 
 generating, by the application, the barcode utilizing the encrypted authorization token. 
 
     
     
       16. The method of  claim 15 , further comprising:
 displaying, by the application, the barcode on a display. 
 
     
     
       17. The method of  claim 15 , wherein the barcode is pre-configured by the authorization token to authorize a single transaction. 
     
     
       18. The method of  claim 17 , wherein the barcode and the authorization token are configured to expire after the authorization of the single transaction. 
     
     
       19. The method of  claim 18 , wherein the transaction is a payment transaction and the authorization token is a payment token, and wherein the payment token is associated with a monetary limit. 
     
     
       20. The method of  claim 19 , further comprising:
 transmitting, by the application, the encrypted data to the server prior to receiving the verification of the encrypted data; and 
 decrypting, by the application, the encrypted authorization token to authorize a transaction.
